维也纳整流器是一种非发电升压型整流器，用于许多应用，例如电信系统和风力涡轮机系统。维也纳整流器有特殊的操作要求。考虑到这一要求，提出了许多切换方法。这些方法通常考虑维也纳整流器以单位功率因数的操作，因为维也纳整流器旨在向负载提供功率。然而，由于维也纳整流器的应用是多样化的，控制要求已经提出，包括直流母线电压平衡控制和严重不平衡电网下的新控制。在本文中，我们提出了一种基于载波的脉宽调制（CB-PWM）的方法，维也纳整流器操作与可变功率因数。所提出的CB-PWM方法根据功率因数将补偿电压添加到三相参考电压，以保持维也纳整流器的正弦输入电流。通过仿真和实验验证了所提出的CB-PWM方法的性能和有效性。
The Vienna rectifier, which is a nongenerative-boost type rectifier, is used in many applications such as telecommunication systems and wind turbine systems. The Vienna rectifier has a special operating requirement. Many switching methods considering this requirement were proposed. These methods generally take into account the Vienna rectifier's operation with the unity power factor because the Vienna rectifier aims to provide the power to the load. However, as the applications for the Vienna rectifier are diversified, control requirements have been suggested, including the dc-link voltage balance control and the novel control under severely unbalanced grids. In this paper, we propose a carrier-based pulse-width modulation (CB-PWM) method for Vienna rectifier operation with a variable power factor. The proposed CB-PWM method adds the compensation voltage to the three-phase reference voltages, depending on the power factor, to maintain the sinusoidal input currents of the Vienna rectifier. The performance and effectiveness of the proposed CB-PWM method are verified by simulation and experiment.
